To measure how much energy is used when a 100-watt light bulb is on for 5 hours, the solution is 100 watts x 5 hours = 500 watt-hours. A Kilowatt-Hour (kWh) is equal to 1,000 Wh. If the same light is left on for 10 hours, the energy consumed is equal to 100-watt x 10 hours = 1,000 watt-hours, or 1 kilowatt-hour (kWh).
